Good Morning! Does anyone have a manual to integrate Asterisk with Opera PMS?
No reply for years 
. I’m looking for an integration company too.
It’s difficult to verify the negative. No reply in a situation like this typically means: I don’t think so, but I could be wrong.
You also need to consider that less than a dozen people actually read and reply here, so the chances of their having experience with rare product is small.
Opera PMS turns out to be a hotel property management system. My guess is that people in the hotel industry are more likely to use an Asterisk GUI, like FreePBX, so there may be a slightly higher chance of finding someone on their forums, although, if you are not FreePBX, the answer may not be helpful.
